Cello Key is a simple fingerboard chart application for cello learners. Cello learners are often troubled by the question, "Which note should I press, in which position and with which finger?" The fingerboard chart to refer to at that time has now become an app. Because it is an app, you can carry it with you anywhere and check it anywhere. Furthermore, the simple layout makes it easy to read. You no longer have to worry about finger numbers when playing sheet music that does not have them written on it.
